"Entering" means?

About What do user trust levels do?:

entering at least 5 topics

Hello, I need to undestand what does “entering” mean in Trust Levels.
I thought that TL1 promotion was when the user POST at least 5 topic.

In TL1, I’ve got some users who posts 2 topics and they got the promotion to TL1., so I believe that “entering” is like “reading”?

Can you help me to understand?
“Enter” is like “read” or “post” ?

You can consider “entering a topic” a synonym of “visiting a topic”.
